Genistein glucoside

For example, the mouth is exposed to a substantial, albeit transient and spasmodic, flux of PPT. It has been reported that quercetin-4 -glucoside, quercetin-3-glucoside, phloretin-2 -glucoside, and genistein-7-glucoside can be rapidly hydrolyzed, and quercetin-3-rutinoside...

The most prevalent dietary isoflavones include genistein, daidzein, glyci-tein, biochanin A, and formononetin [Klejdus et al., 2007]. These compounds are primarily found in legumes where they occur as glucosides. This fact may affect the absorption rate of isoflavones and will be discussed in the next section.

Isoflavones are derivatives of the parent compound isoflavone (3-phenylc,hromone 3-phenylbenzopyran-4-one). The dietary isoflavone phytoestrogens (notably from soya bean) that bind to the oestrogen receptor are the best known, namely daidzein (7,4 -dihydroxy-isoflavone), genistein (5,7,4 -trihydroxyisoflavone) and glycitein (7-hydroxy-6-methoxy-isoflavone) and their respective pro-phytoestrogen 7-0-glucoside precursors daidzin,...
